Active Power Inc (ACPW) announced that it successfully operated a prototype of its new battery-free energy storage system at 10 kilowatts (kW) for over 2 hours, a milestone that positions the new product well for the telecommunications segment.

"The runtime of this prototype system is already 60 times that of our flywheel product and yet offers the same battery-free benefits," stated Joe Pinkerton, Chairman and CEO of Active Power, Inc. "A battery-free system that provides hours of backup time will allow Active Power to pursue the $4 billion telecommunications backup power market." [ more ]
